And it's an interesting point. I see your delimna. I know MANY of the guys at the track use the old "bubble balance" as I have also. These guys (and myself) are running over a 100 mph. I've used both methods, the Computer Confuzer model and the bubble balance. The reason for the bubble balance is simple. We don't have a "Confuzer" at the track and, like myself, many of us are changing wheels\tires AT the track.

When I get those new shiny tires and I'm all excited I do the Computer Balance. Once the "newness" wears off and reality sets in, I use the Bubble. Works about the same as far as I can tell and is a LOT cheaper!
